Assign stimuli to lists and a randomised, reproducible trial order

Dispatches on the design's paradigm: the factorial recipe for matched word lists, or a Latin square over conditions for paired/sentence paradigms.

Usage

counterbalance(stimuli, design, schema, list_of_set = NULL)

Arguments

stimuli

A stimuli data frame (matched set or loaded item table).

design

A parsed design configuration.

schema

The parsed global schema (provides the seed).

list_of_set

Optional named integer vector mapping each set to a list, from balance_lists(). Supplied by the pipeline when counterbalance.optimise is on; when NULL the factorial recipe deals sets to lists by rank as before.

Value

stimuli with added list and trial columns.
